PEX Expansion Fittings are used for floor heating main pipes for hot water systems. It has good thermal insulation performance. Because PPR is a random copolymer polypropylene synthesized by gas phase method, its structure is characterized by the random linkage of PE molecules among PP molecules, and the molecular weight is from 300,000. ～800,000, but because PPR pipes are not flexible enough, they cannot be coiled like PEX and PERT, so they can only be turned with elbows, and it is stipulated that joints are not allowed under the ground during the construction of the floor heating system, and they cannot For bending construction, if the pipeline is laid for a long distance or has many corners, a large number of joints will be used in the construction.

Generally speaking, the aluminum-plastic PPR pipe adopts a five-layer structure. The outer layer is PPR, the inner layer is PE-RT, and there is an aluminum layer in the middle, and between the layers, It is made of hot melt adhesive and extruded and compounded through high temperature and high pressure to have a good compound effect. This kind of pipe has the advantages of plastic pipes and metal pipes. It can be said that plastic pipes are combined with metal pipes. The advantages of metal pipes are combined to improve the performance of pipes as a whole.

Close the main valve of the PPR pipe, and press the floor heating pipe with a pressing machine. Wait for half an hour when the pressure is 8-10 kg. If the pressure remains the same, it means that the pipe does not leak. Secondly, determine the location of the floor heating pipe. Under normal circumstances, if the floor heating pipe If there is water leakage, the pressure gauge will lose pressure in a short period of time. When it is determined that it is a slow leak, the pipeline should be stopped first, and after the floor heating surface has cooled down, the pressure on the water divider will be closed after injecting pressure with hot water. Valve, observe the pressure gauge and make sure that the pressure gauge has not changed.

After determining the location of the leakage point of the PVC pipe, close the water inlet and outlet valves of the floor heating pipe, and then let the residual water out of the floor heating pipe. Then find the floor heating installer to pry open the floor, plan the cement layer, and connect the leaking point with a joint, such as water leakage. In serious cases, the pipe needs to be replaced. After the repair is completed, the floor heating pipe needs to be pressure-tested again to ensure that no water leaks, and a water flow test is performed to prevent debris from entering the pipe and causing blockage. The PPR pipe is made of random copolymer polypropylene and extruded Become a pipe, injection molded to be a pipe fitting.

The company’s main products are high-density polyethylene PE pipes and fittings; PPR pipes and fittings; aluminum-plastic PP-R pipes, PE-RT floor heating pipes; PVC-U drainage pipes, fittings, PVC-U electrical casing, and PE communication pipes . The products have won many honorary certificates at the provincial and municipal levels. The products sell well all over the country and are well received by users.

PPR pipe RPAP5, which is an aluminum-plastic pipe, and is a heat-resistant water pipe and composite pipe, can be used at a high temperature of 95 degrees, and its working pressure is 1,6MPa, which is between it and PPR pipe , If you compare, then there is a big difference, because the raw materials, conditions of use and purpose are not the same, so this conclusion can be reached, and PPR pipes are used Different materials, therefore, these two pipes are different in material.

The welding heating time of PVC pipes and PE pipes has a corresponding standard, which is the "Technical Regulations for Polyethylene Gas Pipeline Engineering". As for the SDR mark on the pipe, it is from a professional point of view. Refers to the standard size ratio, which indicates the ratio between the outer diameter of the pipe and the wall thickness. For example, SDR11, PE pipe indicates the ratio between the outer diameter and the wall thickness of the pipe, which is 11. PE pipes can be retested Reported, but it is not required.

In order to implement the "plastic strip steel" product plan, Jiangtong has invested heavily in introducing domestic advanced PE production and testing equipment, and the quality of the PE pipes produced is excellent. The pipeline can completely solve the corrosiveness of traditional cast iron pipelines, the leakage of cement pipelines and the toxicity of PVC pipelines.
